| dc.description.abstract | The present investigation was undertaken to study the effect of sowing time and integrated weed management on growth and yield of garden pea. The experiment comprising of 20 combinations i.e. four sowing dates (3rd week of October, 1st week of November, 3rd week of November and 4th week of November) and five weed control treatments viz. weedy check, weed-free (3 hand-weedings), imazethapyr 100g/ha (pre-emergence), imazethapyr 75g/ha (pre-emergence) followed by clodinafop 60g/ha ( post-emergence 45-60 DAS) and imazethapyr 75g/ha (pre emergence) + hand weeding was conducted in complete randomized block design with three replications at the Research Farm of Department of Vegetable Science and Floriculture, CSKHPKV, Palampur during rabi 2021-22. Date of sowing and weed control treatments exhibited significant variation on different growth and yield parameters of garden pea. Results revealed that weed count and dry matter accumulation increased with advancement of crop growth and delay in sowing time from 3rd week of October to 4th week of November. Weed-free (3 hand-weedings) and imazethapyr 75g/ha (pre-emergence) + hand weeding provided better weed control compared to the other treatments. Among sowing dates, 3rd week of October resulted in maximum number of primary branches per plant, number of nodes per plant, plant height, number of pods per plant, pod length, number of seeds per pod, pod yield per hectare, shelling percentage, protein content, gross returns, net returns and benefit cost ratio. Among weed control treatments, weed-free (3 hand-weedings) and imazethapyr 75g/ha (pre-emergence) + hand weeding were the most promising treatments for number of pods per plant, pod yield, shelling percentage, haulms yield, seed yield per plant and 100-seed weight. Three hand-weedings (weed-free) gave highest gross returns (2.80 lakh/ha) but highest net return was found in imazethapyr 75g/ha + hand weeding (1.86 lakh/ha). Highest benefit cost ratio was found in imazethapyr 75g/ha + hand weeding (3.08) due to the high labour cost. The interaction effect between sowing dates and weed control treatments reaveled that the new genotype of garden pea, APL5-55 must be sown between 3rd week of October and 1st week of November with application of imazethapyr 75 g/ha + hand-weeding. | en_US |
